1、首先得引入CoreLocation系統(tǒng)框架

2赴肚、導(dǎo)入頭文件 遵循代理

import <CoreLocation/CoreLocation.h>

<CLLocationManagerDelegate>

3届谈、在info.plist中打開定位權(quán)限

3垄提、代碼實現(xiàn)

@property (nonatomic, strong) CLLocationManager* locationManager;

- (void)viewDidLoad {
    [super viewDidLoad];
//檢測定位功能是否開啟
    if([CLLocationManager locationServicesEnabled]){
        
        if(!_locationManager){
            
            self.locationManager = [[CLLocationManager alloc] init];
            
            if([self.locationManager respondsToSelector:@selector(requestWhenInUseAuthorization)]){
                [self.locationManager requestWhenInUseAuthorization];
                [self.locationManager requestAlwaysAuthorization];
                
            }
            
            //設(shè)置代理
            [self.locationManager setDelegate:self];
            //設(shè)置定位精度
            [self.locationManager setDesiredAccuracy:kCLLocationAccuracyBest];
            //設(shè)置距離篩選
            [self.locationManager setDistanceFilter:100];
            //開始定位
            [self.locationManager startUpdatingLocation];
            //設(shè)置開始識別方向
            [self.locationManager startUpdatingHeading];
            
        }
        
    }else{
        UIAlertController *alertView = [UIAlertController alertControllerWithTitle:@"您沒有開啟定位功能" message:nil preferredStyle:UIAlertControllerStyleActionSheet];
        [alertView addAction:[UIAlertAction actionWithTitle:@"確定" style:UIAlertActionStyleDefault handler:nil]];
        [self presentViewController:alertView animated:YES completion:nil];

    }
}

這里返回一個[placemark addressDictionary]的字典 打印一下可以看到字典里面的各種key领炫，想用哪個key直接替換掉即可

//反地理編碼
- (void)reverseGeocoder:(CLLocation *)currentLocation {
    
    CLGeocoder* geocoder = [[CLGeocoder alloc] init];
    [geocoder reverseGeocodeLocation:currentLocation completionHandler:^(NSArray *placemarks, NSError *error) {
        
        NSLog(@"array == %@",placemarks);
        
        if(error || placemarks.count == 0){
            NSLog(@"error = %@",error);
        }else{
            CLPlacemark* placemark = placemarks.firstObject;
            NSLog(@"dic == %@",[placemark addressDictionary]);
            NSLog(@"placemark:%@",[[placemark addressDictionary] objectForKey:@"Street"]);
            UIAlertController *alert = [UIAlertController alertControllerWithTitle:@"您的位置" message:[[placemark addressDictionary] objectForKey:@"Street"] preferredStyle:UIAlertControllerStyleAlert];
            [alert addAction:[UIAlertAction actionWithTitle:@"確定" style:UIAlertActionStyleDefault handler:nil]];
            [self presentViewController:alert animated:YES completion:nil];
        }  
    }];  
}

//定位成功以后調(diào)用
- (void)locationManager:(CLLocationManager *)manager didUpdateLocations:(NSArray *)locations {
    [self.locationManager stopUpdatingLocation];
    CLLocation* location = locations.lastObject;
    [self reverseGeocoder:location];
}
